19 Now we know that whatever the Law says, it speaks to those who are under the Law, so that every mouth may be closed and all the world may become accountable to God; 20 because by the works of the Law no flesh will be justified in His sight; for through the Law comes the knowledge of sin (Romans 3).
Years ago, while working with a fire equipment company, I was out with my boss checking on an automatic kitchen system we had installed in a restaurant. When told to cut the piece holding two wires together, I cut one of the wires instead. Big mistake, and there was absolutely no escaping it! I had messed up badly, and there was just no way out of it. I could neither undo it, nor hide it, nor make excuses for it. I was busted, pure and simple, and all I could do was admit my mistake before my boss.
This is what God’s Law does. It is has a dual role of both light and muzzle: it shines a light upon our sins, and it also shuts our mouths in trying to justify or undo them. It speaks only truth and does not bow to any falsehood spoken against it. It has the final say in the matter, period. It catches us red-handed, and will not let us go.
Lord, Your Law is indeed a light upon our sins for our eyes to see, and a muzzle on our mouths to keep us from making any excuses. At any time the light of Your Law might shine on us This Day, help us to acknowledge our sin honestly, to repent of it quickly, and to move on thankfully in the grace You supply. Amen.
